'Specification forming part of Letters Patent No. 48,134, dated June 6,li.

To all wlionttfniayconcem: l

Be it knownV that uI, DAN READ, of the city` i and State'otNew York,have invented a new and useful -'improvement in the construction otrolls used Vin preparing wool, cotton, alud.l other fibrous materialsfonspinniug, 'spinning yarn, and manufacturing cloth,

My invention consists in making these rolls of elastic gums compoundedwith sulphur and other substances und coveringthem with leathl:

-er, parchment, orpaper, or the equivalentof either, in such a mannertliutwhile the'muin' body of the roll is left elastic nndyielding the'outer surface is tirm and smooth.

Heretoi'ore, when the body of the rolls has been formed of'elustcmaterials, the leather or other covering, made -ot' mnterials differingfrom that of which thebody of the roll is formed and formingthe outersurface, has been put on after the body 'was iinished I.ind vulcanized,and fastened attheends oi' theroll only, thus leaving the intermediatespace which-comes into -cpntact withthe yarn or cloth loose und liable Ato friction between the body ot' the roll and the covering. ThisrIremedy by making the or paper, or their equivalents, adhere to theelastic body, so that the4 4 roll and cover, when completed, form oneentire mass. i

To enable others skilled in the art to practice luy-invention, I willproceed to describe it.

In the accompanying drawings, forming part `oi' this specification, A Ais n shui't or spindle, hnvingon itone complete roll, B, and one havingVa. portion cut olii, so as to, exhibit the body U nud covering D.

lows:

A. A is n shaft or spindle, with bearingsto es will neo-l circumference.

The construction undoperat'iou nre ns fol. i

essarily dier in length and size. There may be flanges on these shaftsizo-form the rolls be tween, or the rolls may be formed around. the'shafts without them. Around the shaftorspindle, between the flanges, orwhere Bauges are y i omitted, at the required position on the slix'aft,

I 'fo'rm 4the body of the roll `ofa preparation made of gatta-perche.,india-rubber, or other fibrous or globular gums prepared with suiphurand other substances well known to p ery v the art of preparing gumsfort- 'vulcanz'atiou, of the consistency'ot putty, un

lf anges sons skilled in til the required `body is obtained. are used,this body should extend beyond t eir thus formed I put u covering ofleather, parchment,' or paper, or the equivalent 'of' either, closelyfitted und nenti y joined, around it, covering its' entiresurface, andthen apply to the roll so covered steam or peratureofubout260Fnhrenheit.Thiscauses l the material used in covering to unite with and adhere toit so iirrnly'that the whole becomesV heated nir at a temone entiremass, having'au uniform 4elastic with the required surface for thevarious usesV to which the roll is to be applied.

Thedegree of heat will, of course, be'varied' according 4to theproportion ot' sulphur ,and othersubstances in the compound, and alsoaccoi-din g to the different degrees of elasticity refy quired. Y

Havingthus described the rolls and the inode of constructing them, whatI claim as new, and

Covering rolls for preparing materials for i spinning and spinnin'gynrnund manufncton nicloth with en inner covering of vulcanized u ber,gotta-perche, or other suitable gums, and with un outer corel-in ofleather, porcha mehr, paper, or4 the equivs ent of eitherI these twocoverings bein .united to 'ether in. the manner as and for t e purposeascribed.
